摘要： It is known to isolate MHA from a reaction mixture obtained by the addition of hydrocyanic acid (HCN) to methyl mercaptopropionic aldehyde (MMP) and the hydrolysis of the methyl mercapto propionic aldehyde cyanohydrine (MMP-CH) obtained thereby with sulphuric acid, in which the reaction mixture is brought into contact with a substantially non-water-miscible organic solvent, in order to form an extraction solution having the solvent and MHA transferred from the reaction mixture, and the MHA is obtained as an extract from this extraction solution by concentration. The simplest and most economical process of the invention concerning the processing of the reaction product which facilitates the production of a highly concentrated product with an extremely low dimer, oligomer and by-product content, is characterised in that the concentration is conducted in such a way that the remaining extract contains less than 4 wt % and preferably less than 2 wt % of water. Animal feed supplement, mixtures for supplementing animal feed, e.g. with methionine or ammonium-MHA.

摘要： Process for producing ammonium-2-hydroxy-4-(methylthio)-butyrate, mixtures containing the same in liquid form and their use. Processes are known for producing ammonium-2-hydroxy-4-methylthio-n-butyrate (MHHAS) by treating 2-hydroxy-4-methylthio-butyric acid (MHA) with ammonia or by isolating MHA, which also contains dimers and higher oligomers, from a reaction mixture obtained by adding hydrogen cyanide (HCN) to methylmercaptopropionic aldehyde (MMP) and by hydrolysing in mineral acid conditions the thus obtained methylmercaptopropionic aldehyde cyanhydrine (MMP-CH). In order to produce ammonium-2-hydroxy-4-methylthio-n-butyrate and mixtures containing the same with a remarkable fluidity and a very low oligomer proportion by a process based on exclusively "liquid" steps, the reaction mixture is treated with a water-immiscible or partially water-miscible inert solvent, until a first organic extract and a first aqueous raffinate are obtained, and the first organic extract is decomposed into a second organic extract and a second aqueous raffinate by treating it with ammonia and phase separation. Re-extraction of MHA as MHAAS is carried out in the second aqueous raffinate, causing salt formation, and MHAAS is isolated from the second aqueous raffinate. This compound is useful as feedstuff supplement and as methionine substitute.

摘要： The invention relates to a process for improving the storage stability of sodium percarbonate (2Na2CO3.3H2O2) by encasing it in sodium perborate. According to the invention, sodium percarbonate wet salt, obtained by the reaction of soda with hydrogen peroxide in the aqueous phase and separating the salt from the aqueous phase, is treated with a sodium perborate-containing solution or suspension in a solid-liquid separation device according to a process of displacement wash. The invention provides longer storage stability with a thinner perborate coating than prior art processes.

摘要： In a process for manufacturing gas-tight aluminium tubes suitable for carrying out catalytic high-temperature reactions, powdered aluminium oxide is mixed with water, a binder and a plasticizer, and the mixture is deformed by drawing a hank into a cylindrical green body, which is then deformed in at least two places so that the circular cross-section of the tube becomes approximately ellipsoidal. The deformed green body is dried and sintered at 1740°C. Excellent mixing of the gas in the tube is achieved as a result of the constrictions in the cross-section.

摘要： In order to reduce the soot content of a diesel engine's exhaust gas, a fluid containing a peroxide compound, preferably an aqueous hydrogen peroxide solution, is fed into the combustion chamber after the start of the injection and combustion of the fuel, preferably following the combustion phase. The diesel fuel is preferably injected in the range 10 DEG +/- 5 DEG before top dead centre and the fluid containing the peroxide compound is fed in the range 5 DEG to 30 DEG after top dead centre. Use may be made for the alternate supply of diesel fuel and hydrogen peroxide of a shared injection nozzle (fig. 1) which supplies one or other of the media depending on the pressure of the diesel fuel and hydrogen peroxide solution supplied.

摘要： The invention relates to novel highly effective activators based on phenolic and enolic O-acyl compounds for peroxo compounds, activator compositions and washing, bleaching, cleaning and disinfecting agents containing these activators. The activator effect of phenolic O-alkanoyl compounds is greatly reduced if the chain of the alkanoyl group contains more than 9 to 10 C atoms. The phenolic and enolic activators of the invention contain the undecenoyl radical or an alkadienoyl group with 5 to 17 C atoms as the O-acyl group. The activator 4-undec-10-enoyl oxybenzole sulphonic acid or a water-soluble salt thereof is substantially more effective than the corresponding activator with an undecanoyl group. Activator mixtures of an activator of the invention and one based on an O-acyl or N-acyl compound exhibit synergistic effectiveness.
